Disponível em: http://repositorio.ipen.br/handle/123456789/16369.http://repositorio.ipen.br/handle/123456789/16369A Neural Network structure has been used for unfolding neutron spectra measured by means of a Bonner Sphere Spectrometer set. The present work used the ‘‘Stuttgart Neural Network Simulator’’ as the interface for designing, training and validation ofa MultiLayer Perceptron network. The back-propagation algorithm was applied. The Bonner Sphere set chosen has been calibrated at the National Physical Laboratory, United Kingdom, and uses gold activation foils as thermal neutron detectors. The neutron energy covered by the response functions goes from 0.0001 eV to 10MeV. Two types ofneutron spectra were numerically investigated: monoenergetic and continuous. Good results were obtained, indicating that the Neural Network can be considered an interesting alternative among the neutron spectrum unfolding methodologies.252-255openAccessneural networksneutron spectraneutronsbonner sphere spectrometerscomputerized simulationTexto completo de evento10.1016/S0168-9002(01)01464-4https://orcid.org/0000-0003-2478-5757
